Processes responsible of the structural diversity of the Cyperaceae synflorescence: Hypothetical evolutionary trends

Inflorescence structure in Rhynchospora Vahl (Cyperaceae)

“…3). This zonation is in agreement with that found in other groups of Cyperaceae (Guarise and Vegetti, 2008b;Reutemann et al, 2009;Vegetti, 2003).…”

“…The importance of truncation and homogenization processes were recognized in Cyperaceae (Guarise and Vegetti, 2008b). Truncation consists in loss of the distal portion of the inflorescence.…”

Scape anatomical studies in populations of Urginea indica Kunth. Liliaceae

“…The taxonomic value of foliar anatomical features in U. indica has been reported by Mustapha (2000); and on leaf anatomy and systematics of Hyacinthaceae by Anna H. Lynch et al (2006). Ahmet et al (2010) have provided a comprehensive description of the morphological and anatomical properties of Bellevalia paradoxa.Studies on inflorescence morphology and anatomy are common in families such as Poaceae Anton 1995, 2000), Cyperaceae (Guarise and Vegetti, 2008), Aristolochiaceae (Gonzalez and Rudall 2001) but the studies are rare in Liliaceae member U. indica. Anatomy of scape and its potential use in systematics and delimitation of the populations of U. indica has been paid little attention.…”

<b>Volatile constituents of essential oils of <i>Eleocharis pauciflora</i> (Light) Link and <i>Eleocharis uniglumis</i> (Link) J.A. Schultes growing wild in Iran</b>

“…The majority of the species of Cyperaceae are anemophilous and their flowers generally have no scent because of their tiny, inconspicuous flowers and hidden or reduced perianth [3].…”

“…The genus has a geographically cosmopolitan distribution, with centers of diversity in the Amazon and adjacent eastern slopes of the South American Andes, northern Australia, eastern North America, California, Southern Africa, and subtropical Asia [4]. Their subterraneous parts comprise roots and stems (rhizomes or stolons) simple, unramified stalks that end in a dense spiciform inflorescence formed by numerous, very inconspicuous flowers form their aerial parts [3]. Eleocharis species spread by growth of their horizontal stems, as well as by dispersal of seeds and tubers or, in some species, by proliferation of the culm tip [5][6][7].…”
